Only 1.
you get one in icefall cave on four island
If you mean evolution stones. You can buy them at the shop in Celadon
you find every single Pokemon and then you go to her and then you ask twice and she will gve you three moon stones, five fire, and two sun.
1 but if you save it you can duplicate it
There are many stones in pokemon, and many stones have the same rarity. In my opinion, the rarest stone is either the sun or dusk stone.
They can be brought at the Celadon Department Store.
in the celular cave after getting the three stones for island 1
You can get one in mount moon and just look around for the others
there are no dawn stones they were not introduced until Pokemon diamond and pearl
you can't. leaf green is first gen. sunstone wasn't around until second gen. so you can onloy get fire,thunder,water, & Moon stones in leaf green.
You can't as far as I know....
Ditto.
